Art. 73 Cantonal Police Law (LPol)
1 Before the commencement of a criminal investigation by the Public Prosecutor's Office, the cantonal police may conduct secret preliminary investigations if the following conditions are met
a) there are sufficient indications to presume that a crime or an offense could be committed; and
b) other investigative measures have no chance of success or are exceedingly difficult.
2 The measure is ordered by a police officer, for a duration of no more than one month.
3 It can be extended beyond one month only with the approval of the Public Prosecutor's Office.
4 At the conclusion of the measure, all gathered evidence must be destroyed within thirty days if no criminal proceedings have been initiated.
5 Officers assigned to secret preliminary investigations do not use an assumed identity. Their true identity and their function are documented in the case files and disclosed during hearings.
6 The provisions of the Swiss Code of Criminal Procedure apply analogously to the rest, particularly in relation to communication to the person who was subject to the measure.
